Currently what is the best Firewall & Internet security for Ubuntu?

  • Questions about "the best" are generally just asking for opinions, which is not the purpose of this site. – guntbert Nov 4 '13 at 16:57


Ubuntu has an inbuilt firewall caled ufw

The graphical version for it is gufw. Search in the Ubuntu Software Center you will find it

Ufw is installed by default and is one of the strongest firewalls ever

See this Ubuntu Documentation for Firewalls


Regarding an Antivirus software, you dont need one because linux rarely catches a virus.
There are hardly any linux viruses

If you insist on having one for windows files on linux,

Then install Clamav found in the Ubuntu Software Center and the gui frontend for it is clamtk also found in the Ubuntu Software Center.

Check these Ubuntu documentations for more info

  • Worst advice ever- old post to blame, but Linux gets hit by all sorts of things online in the year 2017.Application Firewalls is one way to go... especially with xss attacks, and linux does get hit by Trojans – DDJ Dec 1 '17 at 17:41
